Is it a historical photograph or a photograph published in a book that someone scanned and posted on line, is it a photograph of something like a sculpture? Is your paper focused on the work of the photographer, the makeup artist who prepared the model, the digital image enhancer who altered the image, the model? There is no single correct way to cite a photograph, because there are many different reasons to cite a photograph. Your instructor would be able to give you more specific advice. In general, though, the 8th edition of the MLA guide would say something like this:
• A good paper is the result of a process of writing and revising drafts. For further information and samples, see PHCC Online Writing Center – Essay Organization and Writing Process .
• Research papers must include information from the sources by quoting, paraphrasing, and summarizing in addition to your own analysis and evaluation of that information.
• For further information on how to incorporate information from sources in MLA style, see Quoting, Paraphrasing, and Summarizing . Aside from the differences in the citation itself, this method applies to how to incorporate information into APA style papers as well.
• Every sentence with information from a source must give credit to the source. Otherwise, it is plagiarism.
